Logistics of Paul's massive donation haul
Has any scholarly work been published regarding the practical and logistical implications of Paul's massive donation push? For all intents and purposes he appears to spend YEARS soliciting a tremendous amount of donations from his congregations, often bragging about one church to another in an effort to goad them into giving even more. And in 1st Corithians chapter 9 he even seems to deal with quite a bit of strife from the Corinthian community about his handling of these donation funds, apparently suspecting him of embezzlement. My main point is that this donation collection takes up a tremendous amount of Paul's time and effort over the course of several years. Surely this means that Paul is physically hauling around hundreds of pounds worth of coinage, yes? What would this look like during this time period? How would such valuable coinage be moved by Paul? How would he store it? Wouldn't he be a tremendous target for bandits or unfriendly government officials? Would he need a dedicated team of bodyguards or soldiers to both protect and physically move such large amounts of currency? Are there any books or articles that dive into this logistical aspect of Paul's ministry?
